Note
In designing the layout of the AN-9001, pay particular attention to the following points so that the AN-9001 and
AN-001T in combination can function effectively.
• Position the AN-9001 fully away from the speaker to be used for zone announcement. Doing otherwise may
cause the AN-9001 to detect the speaker sound as noise, failing to keep the optimum sound level.
• Do not position the AN-9001 near the equipment that constantly generates loud noise. If positioned, the AN-
9001 will respond to such loud noise, failing to respond to the change in ambient noise level.
